I thought it a good way to do the Dwarf Fortress succession games. Nice to have revisioning and all that (in case of too much !!FUN!!) And its just fun to say 'For the Fortress!' As in "Why do you need that cannon?" "For the glory of the Fortress! May it hold high the Upper Arm!"
I mostly just wanted to try out the git and see what was the up. It has more features then SVN, but also seems more archaic (like learning regular expressions. The only make any sense after you know everything about them, before, and up to that they are just gibberish.)
